The YF-1 Veritech Prototype was flight-capable testbed and proof of concept for the Veritech fighter, developed for the Robotech Defense Force prior to the First Robotech War. Roy Fokker successfully performed the fighter's first transatmospheric flight. The Prototype was the precursor the the VF-1A Valkyrie, and its subsequent variants, as seen in Robotech: The Macross Saga.
The YF-1 Veritech Prototype was the first mecha that fully incorporated completely functional reconfiguring components that made it a transformable craft. It ended up being the fastest and most versatile of all Robotech Defense Force mecha that fought in the First Robotech War.
After five years of study, the Robotech Research Group (RRG) was finally capable of creating Earth mecha of sufficient power, thanks to operational Reflex reactor designs and better understanding of Protoculture (known by another name at that time) infused circuitry, able to theoretically counter the aliens that were discovered within the Super Dimension Fortress-1 Macross (SDF-1). Data suggested that a fast and manueverable mecha was necessary to counter any future alien incursion. For a while, the research group considered other types of combat vehicles, such as transformable helicopter, and even motorcycles.
In late 2006, flight test began of the VF-X, a new jet frame design incorporating non working components from a transformable version still under laboratory development. The first flights weren't always successful ending in mangled test aircraft and injured or deceased test pilots. These test continued into the next year as they worked out hardware design and wrote software capable of compensating for flight difficulties. By the end of 2007, Roy Fokker tested the VF-1X, a test frame including all Valkyrie components and systems necessary for full transformation, while not always picture perfect he was able to change from Fighter to Guardian modes and on occasion achieve Battloid configuration without the mecha falling on its ass. The YF-1 entered extremely limited production in 2008 with refined pilot assistance AI software and better Protoculture utilization in transformation and battloid systems. That same year the project was pronounced a complete success and the YF-1 entered full production as the VF-1 Valkyrie Veritech.
The Veritech Prototype needed a jet fighter-form to execute its main objective of air combat, as well as a humanoid battloid form to give maximum mobility and versatility on the ground. The RRG incorporated an intermediate form to ease the conversion from airborne to ground mecha, and this Guardian configuration proved to be such a useful merger of the Fighter and Battloid characteristics that it was also used for high-mobility work near the ground, and not just for VTOL landings. The result was in full scale production a full year before the SDF-1's launch date.
The armor of the standard Veritech Prototype was composed of an advanced titanium-steel alloy. The armor stopped all small arms fire, provided good protection against heavier infantry weapons, such as a 12.7mm machinegun round, and fair resistance to light mecha-mounted weaponry, such as the Zentraedi 22.3mm HE autocannon round.
The Veritech Prototype provided full protection from nuclear, biological, and chemical hazards, using an overpressure cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions was anticipated. The internal consumables supplies could provide atmosphere for two days maximum.
- The VF-1 (which the YF-1 Veritech Prototype was based on) was created by the renowned Japanese mecha designer Shōji Kawamori (with contributions by his Studio Nue partner Kazutaka Miyatake) in 1980-1982 to be the centerpiece mecha design of the anime series The Super Dimension Fortress Macross (1982–1983).
- The McDonnell Douglas F-15 Eagle and Grumman F-14 Tomcat with its variable-sweep wing design, served as the main design inspiration of the VF-1.
- The name "Valkyrie" was a tribute to the real world XB-70 Valkyrie, an experimental supersonic strategic bomber developed in the United States in the 1960s.
- In Robotech (the 1985 American adaptation of Macross), the VF-1 was most commonly referred to as a "Veritech Fighter", with "Veritech" being short for Variably Engineered Reflexive Induction TECHnology, but the fighter's more popular name was "Valkyrie", used by Captain Henry Gloval in the episode Bye Bye Mars.
